I've got a question reguarding some math of forces and such.  Here's the problem.  I'm trying to quantify the forces at work with the following fighting robot weapon.  I'll cut to the chase, and keep it theoretical, i don't have the exact numbers quite yet, but this'll give me an idea of the math involved.

Weight of moving object: 12.5 lbs
Speed of Weight: 10 fps
Time taken to impart all latent g-forces: .005 seconds


Anyone?

I don't think "force" is what you're looking for as much as perhaps momentum?

Momentum is expressed as mass times velocity.

p = mv

In this case, mass = 5.67kg (converted from pounds), and velocity being the 3.048m/second (converted from fps) you mentioned.

(5.67kilograms) x (3.048m/second) = 17.28kg-m/second


Why do you want to know?

Probably has some design schematic for his Fighting Kung-Fu Ninja Robot that he plans to unleash upon the world and revel in its undoing as he crowns himself 'Lord Of Earth'.

But I just dunno...

If you've ever watched Big O on Adult Swim, you might know where i got this idea.  The basic idea is to make a robot for something like battlebots or robot wars, with a basic 2-wheeled hammer design, allowing it to spin at high speeds.  i'm not worried about initial impact, the math on that is the same way, basically, but i had a thought.... what if i were to toss in a pneumatic or hydroulic ram that triggered on impact, with some sort of weight that it slammed to add a little more forcei figured out the center of mass problems that it might cause, but beyond that, all i gotta do is house it, and it'll be good to go.  i just wanted to know if it would be worth the time and money to put it together.
